bugfix - fix broken output in expanded aligned format, when data are too short

[Pavel Stehule]

Hi

There is a bug in fe_utils

(2026-03-23 20:36:21) postgres=# \pset
border                   2
columns                  0
csv_fieldsep             ','
display_false            'f'
display_true             't'
expanded                 on
fieldsep                 '|'
fieldsep_zero            off
footer                   on
format                   aligned
linestyle                unicode
null                     '∅'
numericlocale            off
pager                    1
pager_min_lines          0
recordsep                '\n'
recordsep_zero           off
tableattr
title
tuples_only              off
unicode_border_linestyle single
unicode_column_linestyle single
unicode_header_linestyle double
xheader_width            full

the bugfix is really short

PRINT_ALIGNED)
    {
        unsigned int swidth,
                    rwidth = 0,

after fix:
